    The multi-subunit GID/CTLH E3 ubiquitin ligase promotes cell proliferation and targets the transcription factor Hbp1 for degradation

    Fabienne Lampert et al.
    Proteomic, biochemical and cell-based analyses of the heterodecameric core GID/CTLH E3 ligase complex reveal its molecular architecture, activity determinants, and function in targeting the tumor suppressor Hbp1 and other substrates required for cell proliferation.

    Gene family innovation, conservation and loss on the animal stem lineage

    Daniel J Richter et al.
    The genomes of animal progenitors evolved as mosaics of old, new, rearranged, and repurposed protein domains, genes and pathways and paved the way for the origin and evolution of animals.
  1. Episode 46: March 2018

    In this episode we hear about autism, insulin resistance, Sci-Hub, coping with low levels of oxygen, and how the brain responds to blindness.

    Sorting of a multi-subunit ubiquitin ligase complex in the endolysosome system

    Xi Yang et al.
    A single transmembrane E3 ligase complex can regulate protein ubiquitination at multiple organelles using interchangeable targeting subunits.

    The last common ancestor of animals lacked the HIF pathway and respired in low-oxygen environments

    Daniel B Mills et al.
    Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.

    Evolution: Oxygen and early animals

    Kalle T Rytkönen
    The biology of sponges provides clues about how early animals may have dealt with low levels of oxygen.

    ME31B globally represses maternal mRNAs by two distinct mechanisms during the Drosophila maternal-to-zygotic transition

    Miranda Wang et al.
    ME31B is a general repressor of gene expression in the Drosophila early embryo, repressing translation before the maternal-to-zygotic transition and stimulating mRNA decay after activation of the zygotic genome.

    Na+ influx via Orai1 inhibits intracellular ATP-induced mTORC2 signaling to disrupt CD4 T cell gene expression and differentiation

    Yong Miao et al.
    Non-specific sodium entry inhibits T cell receptor induced gene expression and differentiation of T cells by depleting intracellular ATP and disrupting mTORC2 dependent signalling axis.

    Electrostatic anchoring precedes stable membrane attachment of SNAP25/SNAP23 to the plasma membrane

    Pascal Weber et al.
    A step of contact establishment preceding stable membrane attachment by palmitoylation is identified.

    Structural basis for the hijacking of endosomal sorting nexin proteins by Chlamydia trachomatis

    Blessy Paul et al.
    Chlamydia hijacks membrane trafficking proteins of the human host via the cytoplasmic domain of a secreted transmembrane protein.
